Glucose, which is a six-carbon sugar, is at that moment divided into two molecules of a three carbon sugar. The breaking down of glucose, takes place in the cell’s cytoplasm. Glucose and oxygen are produced from this breakage, and are supplied to cells by the bloodstream. Also produced by glycolysis are, 2 molecules of ATP, 2 high energy electron carrying molecules of NADH, and 2 molecules of pyruvic acid. Glycolysis happens with or without the presence of oxygen.
The Digestive System The digestive system is a system consisting of the mouth, oesophagus, stomach, gallbladder, small intestine, large intestine, the rectum and the anus. The functions of the digestive system are: • To break down food particles into molecules for digestion • To absorb into the bloodstream the small molecules produced by digestion • To eliminate un digested and unabsorbed foodstuffs and other waste products from the body The full digestive process begins at the mouth. The food enters the mouth and is chewed. This is call mastication and it gives the food a greater surface area which enables enzymes to break the food down making it easier to digest. The process of breaking down the food starts with the saliva in your mouth.
• Carbohydrate metabolism: • Gluconeogenesis: The formation of glucose from certain amino acids, lactate and glycerol. • Glycogenolysis: The formation of glucose from delglucógeno. • Glucogenosíntesis: The synthesis of glycogen from glucose. • Elimination of insulin and other hormones. • Lipid Metabolism: • Cholesterol synthesis.
The process of digestion starts in the mouth, then makes its way to the stomach and large intestine, and concludes in the small intestine. At each step along the way, specific enzymes break down specific types of food. This process is chemically balanced as each site along the digestive tract has a different degree of acidity that allows certain enzymes to function while restraining others. Each specific enzyme can bind to only one specific substrate, or group of allied chemical substances. After leaving the stomach, food pulp enters the upper portion of the small intestine where the pancreas (digestive organ that feeds enzymes into the gut) provides pancreatic enzymes to further break down the
There are enzymes located on the intestinal brush border known as ferrireductases which reduce ferric iron to the more soluble ferrous state. Once reduced, the ferrous iron is then transported across the mucosal cells by the transporter protein divalent metal cation transporter 1
When BGLs are high, beta cells (which are also secreted by the pancreas) detect this change. They then release insulin into the blood, the insulin causes the liver to reabsorb excess glucose and convert it into glycogen, the stored form of glucose. Insulin also causes the body 's other cells to take up glucose so that it can be used up, thus lowering the BGL in the body back to the normal
In the human body, one of the essential systems is the digestive system, which breaks down the foods what we eat into nutrients such as proteins, carbohydrates, vitamins and fats. The bloodstream would be absorbed by them. Therefore, it provides the body with energy, repair and growth. Also, the three types of processes that food passes through in the human body are digestion, absorption and elimination. The digestive system prepares the body cells for nutrients through six activities: Ingestion, Mechanical digestion, Propulsion, Chemical digestion, Absorption and Defecation.
Due to the this procedure we know that the digestive system functions with an alliance to the salivary gland, In the beginning of digestion the gland releases saliva, which contains amylase, to form the food into a based elementary molecule. It would help continue the next stride of digestion, due to the fact that the low pH levels of hydrochloric acid it alienates the function of amylase which helped us understand how amylase behave under precise variables (pH levels,
Both oesophagus and stomach use voluntary and involuntary movements. Our stomach contains acids known as hydrochloric acid, which helps dissolve and breaks down food. Within the digestive system is organ called liver. This organ filters out the blood that comes from our stomach. The liver is basically safe guard of all the other organs.
Metabolism is divided into 2 categories Catabolism of: breaking down molecules to produce energy. Mostly occurs during more intense training or fasting. When the body takes advantage of all primary energy sources glycogen and glucose, the body starts to breaks down the muscles to make them into a necessary energy. Anabolism: the metabolic pathways that form molecules from smaller units, which requires energy. Examples of anabolic processes as the growth of bone and muscle.
